I cant fathom the idea that someone will grab a camera and not look to see what setting are on the LCD,,, these cameras can easily change setting with the bump of a wheel. Or how can you remember the last settings you put on the camera, and what are the chances that grabbing the camera now will allow for a shot where the lighting and conditions will be exactly the same.

To put this in perspective, there is an option to disable release without lens.

Surely, you are far more likely to notice a missing lens yet the options is there, right? I understand it's for lenses w/o proper contacts or astrophotography ... but the option exists!
